To 5 be more fully understood from the following the square end S of the stud S is secured a description, taken in connection with the accam N, against the periphery of which rests companying drawings, forming part hereof, the roll or runner 0, carried at one end of a in which rod P, which rod is slotted, as at R, to the 50 Figure 1 is a side elevational View of a mastud S. During the turning or rotation of the disk T and stud S the cam N will also rotate and the roll 0 will ride over the periphery of said cam and thereby shift the rod P back and forth, the rod P riding by reason of its slot R, on the stud S. The other end of the rod P is pivotally connected by toggle-levers Z with each of the arms F and II. A springstud B or equivalent mechanism serves to keep the roll 0 of the rod P constantlypressed against the periphery of the cam N. This spring-stud B is constructed substantially as shown in Figs. 7 and 8, as follows: In the head E is formed a cup-shaped socket e, from which projects a pin or shaft e, on which is adapted to slide a sleeve 6 secured to the toggle-levers Z and to the rod P. Between the sleeve 6 and cup e is placed a spring 0 which is coiled around the pin or shaft 6, and normally has a tendency to slide the sleeve 6 toggle-levers Z, and rod P to the left-hand end of the machine, and to thus, through said toggle levers Z, open the arms F and II. \Vhen the rod P is retracted by the cam N, the sleeve 6 is also retracted on the pin or shaft 6 against the tension of the spring a In operation, as the disk T revolves it will reciprocate the connecting-rod M and head or block E, the latter traveling between the platform D and upper guide D. As the block E is retracted by the connecting-rod M, the stud S and cam N also rotate, the cam N assuming a position wherein the roller 0 rides to the highest point of its periphery, whereby the rod P is retracted and, through the togglelevers Z, the arms F and II are caused to grip the skin at their operating ends. The stud S and cam N will continue to rotate and the rod P will remain retracted until the connecting-rod M is about to return to its original position, when the high portion of the periphery of the cam N will clear the roll 0 and permit the rod P, through the spring-stud B, to shift in a reverse direction and to thereby, through the toggle-levers Z, open the arms F and II.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine of the character described, a reciproeatory block, two arms each pivoted at one end to said block, a rotatable disk, a rod connecting the block with said disk, a stud pivotally connected with said rod and revoluble with said disk, a second reciprocatory rod, toggle-levers adapted to open and close the arms and operated by said second rod, and a cam secured to said stud and adapted to actuate the second reciproeatory rod during the rotation of said disk, substantially as and for the purposes described.

2. In a machine of the characterdeseribed, a reciprocatorybloek, two arms each pivoted at one end to said block, a disk adapted to be rotated, a stud secured to said disk, a rod secured at one end to said block and pivoted at its other end to said stud, a reeiprocatory rod Padapted to slide on said stud, toggle-levers pivoted to the rod P and to said arms, a cam secured to and rotating with said stud and adaptedto shift the rod and toggle-levers in one direction to close said arms, and a springstud adapted to shift said rod P, and togglelevers in the other direction to open said arms, substantially as and for the purposes described.
